Wilson's No. 1318 from Mupin differs from the Hupeh specimens slightly in the 

 more strongly veined leaves, while Nos. 1172, 2765 and 4327 somewhat resemble 

 in their narrower and longer leaves S. Wilsonii Duthie; that species is, however, 

 easily distinguished by its denser glabrous inflorescence.
